Jack just read an interesting study regarding middle school children's use of computer-animated simulations to learn introductory chemistry. Although he is a physics professor he wants to see if the benefits of simulations are also found in college physics learners. Jack's research topic is best described as a study that:.
a. tests theory.
b. is a replication.
c. is developed thorough library search.
d. comes from personal experiences.

b. is a replication

Explanation:

Replication is the term given to repeating the same research study in different environment  and with changed subject. It is done to decide whether core finding of first study still holds true for other situation and context or not.

here impact of computer simulation helped chemistry students. Now jack  wants to see if simulation van help student in physics or not thus impact of simulation is being researched again and hence it is replication research methodology.

in an absolute  monarchy, the  monarchrules as an autocrat, with absolutepower  over the state and government — for example, the right to rule by decree, promulgate laws, and impose punishments. the  monarch isnominally sovereign but the electorate, through their legislature, exercise political sovereignty.
